To ail fwwm t may concern.'

Y Be it known that I, DAvm A. ANDERSON, a citizen of the United States, residing at Faribault, in the county of Rice and State of Minnesota, have invented certain new and useful Improvements in Driving Tools; and I do hereby declare the following to be a full, clear, and exact description of the invention, suoli as will enable others skilled in the art to which it appertains to and use the same. 0

My vinvention provides an extremely simple and highly eiiicient driving tool p'articularly adapted for use in driving to or from place tubular wrist pins and bushings, but adapted for many other purposes, as will hereinafter more fully appear. Be-

cause of' its most important uses, the tool may be properly designated as a Wrist pin and bushing driver or drift.k For interchangeable application to the projecting end of the driving stem, I provide a plurality of diderent kinds of tools.

In the accompanying drawings, which illustrate the invention, like characters indicate like arts throughout the several views.

Referring to the drawings:

Fig.' 1 is a view chieiy in axial sectionbut with some parts in full plan, showing the improved driving tool;

Fig. 2 is a detail in plan with some parts giiioned, showing a shackle bolt driving Fig. 3 is a detail view in plan showinga spring-expanding blade;

Fig. 4 1s an edge elevation of 4the blade shown in Fig. 3;

Fig. 5 is a plan view of a-nail punch; and Fig. 6 is an edge elevation of said nail punc The driving stem of the tool is preferably a steel rod 7 provided with an outer' l end 8 reduced'for insertion into any one of When it is desired toremove the stem 7 the interchangeable tools hereinafter inward. The riving stem 7 works axially through the bushing 11 and, within the make' hand piece, is provided with a rigidly secured collar 12 that quite closely fits the bore of the handpiece but slides freely therein.

The tool 13 shown in Fig. 1 is especially adapted for driving bushings to place or for removing the same, and, hence, is provide with a conical point and with an axial bore that adapts it to duced end 8 of the driving stem 7 and there to be i'rictionally held by the spring-pressed clutch balls 9.

The tool 14 shown in Fig. 2 is especially adapted for driving out shackle bolts and, hence, is of quite small diameter and quite long and is formed at its bolt-engaging end with a conical point 15 and at its other end with a head 16, which latter has a bore 17 adapting it to be telescoped onto the reduced end 8 of the driving stem 7 be telescoped onto the re- The spring-spreading blade 18 shown in Figs. 3 and 4, at one end, has a sharp edge and at its other end is formed with a socket 19that is adapted to be telescoped onto the reduced end 8 of the driving stem. The nail punch 20 shown in Figs. 5 and 6 is provided at one end with a socket 21, adapted to be telescoped onto the reduced end 8 of the driving stem.

The use of he various interchangeable tools noted Vwill be obvious. Of course, the tool proper will be placed against the objectto be driven or displaced, and the operator will usually hold the said tool in position by gripping the outer end of the driving stem 7 and holding the same against axial movements while the heavy hammer-acting handle 10 is reciprocated and driven against the other end of said stem. In the use ot this tool, bushings, shackle bolts and the like may be driven out or driven in under tight fit without damaging the same, and other work ma be similarly performed.

from the tubular hand piece, it is only necessary to reciprocate the tool so as to cause inner'end of said with the inner end of said annular plug, the stem projecting beyond y within said handle for movement in'both direction and engageable eeid collar and being arranged to strike the mte -plie In testilnon ture.

ral'end of said handle, and a tool apl to the outer end of said stem. 1
